In a fresh account, Audacity's AudioIO ctor calls PortAudio's
Pa_Initialize(), which in turn starts JACK's "jackd" although Audacity
defaults to OSS in the audio preferences. This breaks audio completely.
One can kill jackd, switch from OSS to ALSA in the preferences, but
then gets the same symptoms as in 1.3.3-beta.

-----
Audacity pre 1.3.4 beta (cvs 2007-11-08) contains copies of libmad and
libtwolame, which would need to be stripped. Its ALSA support still seems
to be broken heavily compared with 1.3.2-beta.

-----
Audacity 1.3.3 beta is in branch "audacity-1_3_3-test" only
( cvs co -r audacity-1_3_3-test audacity ) as it doesn't work
as good as 1.3.2 beta. The ALSA driver in PortAudio determines
inappropriate sample rates.
